  • R1 and R2 are the same or different and are z.
  • B for hydrogen, C1-C5 alkyl, methyl, ethyl, propyl, i-propyl, butyl, pentyl; Methyl is preferred.

  • the new substances can be converted into the usual formulations, such as solutions, emulsions, suspensions, dusts, powders, pastes and granules.
  • the application forms depend entirely on the purposes; in any case, they should ensure a fine and uniform distribution of the active substance.
